Communication problem

As we can see here when everything is working at max speed in berkeley, we reach the maximum (Avg: 93.49 Mbits/se) and the green graph is flat.

But I can see also that my DL is very very slow.
In theory I can DL at 100Mb, but I see I DL at 30~50Kb

Result is a lot of DL open (hundreds), going slow.

When for any reason Berleley is out of work, I see that suddenly all my pending DL run fast at maximum speed.

So I think that must be someting wrong in how the commnication line is used.
We are too much, trying to pass a little door as in a cinema when someone is shouting "fire!".

Maybe a better usage can see anyone wait for a tiket and then pass data at maximum speed.
Or any other algorithm that can handle better the queue.

Some weeks ago I have seen some posts here about proxy setting. I have tried and for some day I had a good speed. Is this option still valid?

Thanks for the C10K info.
Avery client host can handle two DL in parallel and I use to see from 5 to 20Kb/s speed each, if good, but sometime less than 1.
With BoincTasks I can see all the DL/UL job of my 8 hosts here (other are far)
When berkeley is out of work and the green cricket line is falling down, I see that my DL are 150 to 200 Kb each and so I thing that if you at Berkeley make some filter in order to have only 10'000 clients for each of your DL server, bay be the queue will be used better.
I don't know if you have some "tap" in your communication equipment but if you have, try to set at ~10'000 connection.

Is it possible?

There has been a known problem with the connection for quite some time which Matt has already posted about here,

Speaking of network competition - yes, we're away that we are dropping all kinds of connections during uploads/downloads. This isn't because of our router (which was definitely the problem over the summer before we added RAM to it), but somewhere else further up the pipeline. Still figuring this out, but it's certainly load related.

I have no problem with the slow download myself. But that it's constantly aborted and next put on hold by BOINC for 1-2 hours makes my work-queue almost empty (last task running and only 2 to download).

<--- Searching for this one ;-)

I have upload speed of 5Mbit an download 10Mbit and 6 local machines sharing the connection only one uses the web the others are just running seti and they all have units in the down load cue but none have completed. I think the limit to down load should be only 10 units in your crunch cue and then return one and then get a new one, all my machines are slower and have small hard drives have small hard drives and by the time the do an astropulse unit is like 250+hours Cuda units take like 4 hours per each old 8600gt and its like 5 hrs for the old 9300GE card. the real problem is all these faster computers that do Seti6.03 in very little time and the cuda units in like 30 seconds keep hammering the servers and they can not get any units out. I think that any computer faster than 1.8Ghz core clock be made to do the large astropulse units and leave the small units to us people with old systems as we are no threat to your stats we just believe in the science and are here to support the project

I am running bionic version 6.12.34 (x64)wxWidgets 2.8.10
and the lunatics 0.39 optimized clients. Until I installed the lunatics optimized client and the latest Nvidia 295.73 driver my machines only crunched setiathome_enhanced 6.03 I did not know that my old 9300GE and 8600GT cards did not think they were capable of Doing CUDA. but since I Installed the Lunatics 0.39 x64 client and the latest video drivers this old hardware is crunching setiathome_enhanced 6.10 (cuda_fermi) wu's
I have noticed that as of late the cuda units time has gone down significantly since upgrading the video driver from 285.62 to 295.73.
Now the cuda units range from about 25 minutes up to 1.5 Hrs
With older drivers and the stock client that runs on bionc I never ever got cuda units just the 6.03 enhanced CPU units.

From yesterday, 27 feb, the speed of my connection is 3 times faster.
I didn't make any change here and the green line in Graphs for gigabitethernet2_3 was allways at max level.

It's just like someone closed a litte bit the tap :-) optimizing the data flux

There is a different thread regarding the 295.73 driver update. Many, including me, with bad results.

Just stop BOINC - Uninstall Launatics - Do a 'Clean Install' of the 285.62 driver, and reinstall the Lunatics application.

They are connected through the DVI ports to an 8 port KVM and then the KVM connects to the main keyboard video display and mouse.
Like I said why would I want to change the display driver it works just fine with the two Asus EN8600GT cards and the HP9300GE. Bionc and setiathome_enhanced 6.10 (cuda_fermi)Have no problems with the 295.73 Nvidia drivers with my hardware. In fact the GPU's are actually liking it I have yet to have any computation errors using the 295.73 drivers. Again I ask why would I revert to the old driver because even with Lunatic 0.39 installed and the 285.62 drivers my cards i got no cuda units. With the 295.73 driver I do get cuda units and lots of them, and I do not get computation errors at all with the 295.73 they have bee running error free since I installed them...

I don't know if someone in Berleley have closed (a little) some tap but what I see now is that:
1) data comm graph isn't allways at max speed
2) there are 256,832 results ready to send
3) my hosts have the max of results to crunch
4) I don't have any transfer pending

So this is the ideal condition. :-)
Of course if it is so for everyone!

Is it so?
